“If we didn’t have surveillance, it would’ve gone undetected, or who knows; he could’ve gotten in,” Tristan tells 9News.

The couple had only installed the new doorbell system days before the attempted intrusion.

Ray Hadley from 2GB broke the story, and after the report on 9News’ , police managed to arrest a man for questioning over the incident.

The doorbell system from ring.com cost a couple of hundred dollars, which the couple believes has already paid for itself.

How to protect your home from intruders

We asked Swann Communications' VP of marketing, Jeremy Stewart, how homeowners can ensure their home is safe and secure.

"Home owners and renters should think about a two-pronged safety and security strategy to ensure their loved ones and property are protected," explains Jeremy.

"The first element of this is to employ a handful of free, easy, and common sense steps that you can do straight away."

Have a look at your premises from the point-of-view of a burglar – are there any vulnerable spots that could make for an easy break-in? This will help you determine what type of security you need and where you should set it up.

Lock your home windows and doors, even when you’re at home.

Put security stickers on your windows and near your front door to suggest that your house is being closely monitored by CCTV cameras.

Maintain garden areas by mowing your lawn and trimming hedges. The more exposed your home is, the less burglars will want to risk breaking in out of fear of being seen.

Keep both the inside and outside of your home neat and tidy, and make it seem lived in. This includes making sure your mailbox isn’t overflowing, taking bins out regularly, and making sure valuables and expensive products are out of sight if someone were to look through the window.

Get to know your neighbours, and agree to keep an eye on each other’s properties, especially when you’re on holidays.

"The second part to protecting your home is to install products that make your property more secure," Jeremy adds.

"There is a misconception that a good home security system can cost thousands of dollars, and requires a complex and professional installation. However, this is not the case – there are a number of products in the market that are DIY and much more affordable than you may think."

CCTV cameras – A CCTV system is not only convenient, but can also deter burglars from stepping on your property (or if they do, the camera footage will provide much-needed evidence). CCTV systems (like the one used by Tristan and his family) can be both wired or wire-free. There are compact and affordable options that are battery-operated, wire-free and can be installed yourself. Swann's offering is also has heat and motion-sensing and can generate push notifications to your mobile device and start video recording when activity is detected ($269.95).
A wired CCTV system with multiple HD cameras and Smartphone viewing can be purchased and self-installed (if you have intermediate handyman skills) for under $1000.

Sensor lights with passive-infrared motion sensors – Lighting is a key component within any security strategy. Sensor lights can cost between $30 and $200 and can detect movement of people, animals, or other objects. Some of these are DIY (check before purchasing).

Double insulated deadlocks on doors and windows, which can cost between $60 and $270, depending on whether they are smart (able to be activated by Smartphone) or not.

Video doorphone intercom, so you can screen visitors and buzz people in. Many of these products have the capability to connect to your phone so you can answer the door from anywhere, and record images of visitors that are backed up to the cloud. These cost around $250.
